Does your company have a comedy-writer consultant? No? Well it should.
Varying entities like Virgin Airways, Vitamin Water, Weber Grills, the CIA and Al Gore have hired comedy writers. Yes, Al Freaking Gore. Do you really want your company to seem to have less of a sense of humor than the CIA or Al Gore?
Here is the CIA's first tweet:
"We can neither confirm nor deny this is our first tweet."
Now, I can neither confirm nor deny I am the comedy writer producing that tweet. Just like I can neither confirm nor deny I was the special forces operative who shot Osama bin Laden.
Why have boring boiler-plate, legal drivel on your products when you could give your customers a smile? You can give the same necessary instructions, only funnier.
